MRMV4

Motor Protection with Voltage

The MRMV4 is designed for motor protection applications and has a large package of monitoring and protection functions, such as motor star-up, thermal overload, incomplete start-up sequence. Voltage, power and frequency are supervised as well. The motor temperature can be monitored via an external sensor box (URTD).

MRM4

Motor Protection

The MRM4 is designed for the protection of motors. All the protection functions are based on current. The device offers motor protection functions, such as motor star-up and incomplete start-up sequence.

MCDTV4

Transformer Differential Protection – 2 Windings

The MCDTV4 is designed to protect 2 winding power transformer in substations, distribution and generator applications with a very comprehensive protection package like phase, restricted earth fault, inrush detection, and monitoring functions including grid interconnection and control functionality up to 6 switchgears.

MRDT4

Transformer Differential Protection – 2 Windings

MRDT4 transformer phase and earth fault differential relay is designed to protect two winding transformers in distribution, substation and generation systems. The relay can also be used as a generator and power step up transformer differential protection and also incorporates many backup protection functions.

MCDGV4

Generator Differential Protection

The high precision generator differential protection relay MCDGV4 is designed to protect utilities and industrial generators. The step-up transformer can be easily integrated into the protection (Block Protection) without any extra charge. In addition to the differential protection package and out-of-step protection, the device offers a broad interconnection package as well as full packages for phase, earth, voltage, frequency, distance (backup), and power protection.

New as of Release 3.4: Phase distance (backup) protection, Power Swing Blocking, Load Blinder, Out of Step Tripping (Pole-Slip protection).

MCDLV4

Cable / Line Differential Protection

The MCDLV4 is designed to protect cables and lines up to 24 km. There can even be an in-zone transformer within the line to be protected. In addition, it comes with a very comprehensive protection package like phase, restricted earth fault, inrush detection, and monitoring functions including grid interconnection and control functionality up to 6 switchgears.
